Adding Fractions

A fraction like 1/2 says we have 1 out of the 2 parts the whole is divided into. The top number is called numerator The bottom number is called denominator How to Add Fractions To add fractions there are Three Simple Steps: Make sure the bottom numbers (the denominators) are the same Add the top

Expanded Notation

Definition Expanded Notation is about Writing a number to show the value of each digit. Expanded Notation is shown as a sum of each digit multiplied by its matching place value (ones, tens, hundreds, etc.) Examples 1,234 = 1 × 1,000 + 2 × 100 + 3 × 10 + 4 × 1 98,765 = 9 ×

Rational Function

Definition Rational Function is A function that is the ratio of 2 polynomials. It is Rational because one polynomial is divided by the other polynomial, like a ratio. (Note: the denominator cannot be zero.) Examples Learn More FOIL Method Counting Numbers Difference Multiplicative Inverse Definitions Index

Alternate Exterior Angles

Definition When 2 lines are crossed by another line (Transversal): Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal. How to remember the angle pairs are on Alternate sides of the Transversal, and they are on the Exterior of

Alternate Interior Angles

Definition When two lines are crossed by another line (Transversal): Alternate Interior Angles are a pair of angles on the inner side of each of those 2 lines but on opposite sides of the transversal. How To remember: The angle pairs are on Alternate sides of the Transversal, and they are on the Interior of

Composition of Functions

By combining these 2 function into 1 function, we have performed function composition, which is the focus of this section. Definition of Function Composition Function composition is a method to combine existing functions. Another method is to carry out the usual algebraic operations on functions, including addition, subtraction, multiplication, & division. We do this by
